A friend of mine who used to be self-confident seems a lot more withdrawn than she used to be. Her husband doesn't seem overtly nasty, and I don't think he is violent, but he 'talks over her' a lot, and seems dismissive of her.
For example, I was around their house and the three of us wanted to watch something via i-player. My friend searched the iplayer site for the programme, but instead of taking her word for it, her dh insisted on searching for it himself.
This seems really trivial in itself, I know, but still.
